Umbrella frame with two layers of covers

ABSTRACT

The invention relates to an umbrella frame with two layers of covers, which mainly provides a slider on outer end of a branch rib to connect with inner end of a second rib and to receive a first rib. During closing the umbrella, the second rib will be moved together with the slider alone the first rib inward and then the second with lower cover thereon can be hidden behind the first rib having upper cover thereon. The length of the umbrella frame is also decreased as the umbrella is closed for being capable of use in a folded umbrella.

FIELD OF THE INVENTION

The present invention relates to an improvement of an umbrella frame andparticularly to an umbrella having two layers of covers, which can beutilized in folded umbrellas.

BACKGROUND OF THE INVENTION

It is known that a conventional umbrella with two layers of covers, asshown in FIG. 1 to 3, has an upper cover (1) and a lower cover (2). Byuse of the opening between two covers, wind can pass there through andthe umbrella frame is protected from destroy. The known umbrellaincludes a first rib (31), a second rib (32), and a branch rib (33),wherein inner end of the second rib (32) is pivoted with a connector(311) connected on middle portion of the first rib (31). Anotherconnector (321) is provided on the inner portion of the second rib (32)and is pivoted with outer end of the branch rib (33) having its innerend connecting with a runner (4) around a shaft (5). When the runner (4)is moved downward, the two ribs are closed to the shaft (5) and theumbrella is also closed. Under this conventional structure, the umbrellawith two layers of covers is always used in straight umbrella only. Thetotal length of two ribs will be the same whenever in close or in open.The lower cover (2) is still separated from the upper cover (1) thatwill be trouble however.

SUMMARY OF THE INVENTION

The present invention is to provide an improved umbrella frame toconnect with two layers of covers, wherein the lower cover can bereceived in the upper cover when the umbrella is closed. The design canbe also used in a folded umbrella instead of a straight one. Now,accompanying with the following drawings, the character of the presentinvention will be described here and after.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIGS. 4 and 5, the present invention relates to anumbrella having two layers of covers, which mainly includes a slider (6)on outer end of the branch rib (33). The inner end of the second rib(32) is connected with outer end of the branch rib (33) while the secondrib (32) and the first rib (31) are passing through the slider (6).Hence, the slider (6) with the second rib (32) can be moved alone thefirst rib (31) smoothly. A reinforced rib (34) is provided to connectouter end with branch rib (33) and inner end with inner end of the firstrib (31) and the upper joint (53) of the umbrella.

When to close the umbrella, the slider (6) is moved toward the inner endof the first rib (31), as shown in FIG. 7, and the second rib (32) isalmost hidden behind the first rib (31). It can be understood that thelower cover on the second (32) will be overlapped totally behind theupper cover on the first rib (31). Accordingly, the closed umbrella hasa simple outlook, which can be used or set up more conveniently.

Moreover, in closing state, the second rib (32) is moved behind thefirst rib (31) that decreases the length of the closed umbrella. So theuse of the present invention can be utilized in a folded umbrella withbetter performance. In closed state, an elastic block (51) is providedbetween each tube of the shaft, which can be pressed by the runner (4)during movement that facilitates the closing of the tubes. After theumbrella is closed, as shown in FIGS. 6 and 8, the block (51) as well asthe stop (52) of the umbrella can be covered by the runner for safepurpose.

1. An umbrella frame with two layers of covers including a first ribconnecting with upper cover, a second rib connecting with lower cover,and a branch rib, and the improvement is a slider provided on outer endof the branch rib, the inner end of the second rib being connected withouter end of the branch rib while the second rib and the first ribpassing through the slider, wherein the slider with the second rib canbe moved alone the first rib smoothly.
 2. The umbrella frame with twolayers of covers as claimed in claim 1, when the umbrella is closed, theslider is moved toward the inner end of the first rib and the second ribwith the lower cover is almost hidden behind the first rib and the uppercover.
